TUB functions in signal transduction from heterotrimeric G protein-coupled receptors. It could be involved in the hypothalamic regulation of body weight. This gene encodes a member of the Tubby family of bipartite transcription factors. The encoded protein may play a role in obesity and sensorineural degradation. The crystal structure has been determined for a similar protein in mouse, and it functions as a membrane-bound transcription regulator that translocates to the nucleus in response to phosphoinositide hydrolysis. Two transcript variants encoding distinct isoforms have been identified for this gene.Alias Symbols: rd5Protein Interaction Partner: UBC, SUV420H2, GNAQ, SRC, ABL1, PLCG1, PIK3R1, LCK, JAK2, IRS1, GRB2,Protein Size: 561
